More charges have been filed against a former substitute teacher in Howard County who was originally arrested back in January and charged with child pornography and sex abuse.

Police say Jeremy Sykes, who was a long term substitute at Folly Quarter Middle School, was arrested this morning and charged with 14 counts of sexual abuse of a minor and 50 counts of production of child pornography.

Sykes was initially charged in January after police received information that numerous uploads of child pornography had been traced to a computer at his home and another one at the school where he worked.

Now they say subsequent investigation showed that Sykes was using yearbook photos of students from the school where he taught to replace the faces in images of child and adult pornography.

Police say they've contacted the parents of all of the students involved, and no pornographic images of the students were actually made. Their faces were just pasted into other pornographic shots.
